<p>PROBLEM TO BE SOLVED: To provide a communication method not requiring decoding and storage of a content of a special cell such as an RM cell or an OAM cell by eliminating the need for a cell copy circuit for an exchange to send a cell to plural destination terminal equipments. SOLUTION: In the case of making a multi-point request of a 1st rank destination to be a terminal equipment 20 and an additional destination to be a terminal equipment 30 from a terminal equipment 10, a virtual path identifier/a virtual channel identifier(VPI/VCI) used to send a cell from the terminal equipment 10 to the terminal equipment 20 is set to a header conversion table for the terminal equipment 10 in an exchange 40, used to send a cell from the terminal equipment 20 to the terminal equipment 30 is set to a header conversion table for the terminal equipment 20 in the exchange 40, and used to send a cell from the terminal equipment 30 to the terminal equipment 10 is set to a header conversion table for the terminal equipment 30 in the exchange 40. Thus, a logical loop connection relation is configured to eliminate the need for a cell copy circuit and to eliminate the need for interpretation and storage of a content when cells are confluent.</p> |
